Not sure about your Mustang, but likely cleaning the TB was a good thing. The IAC (idle air control) is something else. I cleaned my IAC on the old Dodge truck regularly, and it was just to wipe off the carbon with a rag, and a dry q-tip into the well. I never sprayed it with anything nor used any cleaner. I'm guessing that plain and simple 91% alcohol might have ill effect. But TB or carb cleaner might. Those sensors can be rather sensitive (no pun intended).
I know very little about the Mustangs let alone my specific model (yet). On my former Dodge truck, I could actually remove the IAC from the TB.
Trouble shooting.......have you driven your Mustang since the cleaning, or just started and let it idle?
I know that the A/C compressor cycling will down the RPMs on mine at a stop and in drive to where I can feel it just for an instant.
Maybe you could try the battery disconnect ordeal that's so often spoken about to see if that changes anything.
At some point I'll be wanting to clean my TB properly as well. I know all too well that sometimes you can open a can of worms.
Hopefully you'll get some good input on this ordeal. More than likely it's happened to someone else. I have a 2011 V6.
